Refractor telescopes
Refractor telescopes are a classic and widely recognized type of telescope known for their sleek and elegant design. These telescopes utilize a combination of lenses to gather and focus light, providing clear and sharp images of celestial objects.
Key features of refractor telescopes
Refractor telescopes come with distinct attributes that set them apart from other types.
Here are some of the notable features of a refractor telescope:
Objective lens
The refractor telescope’s primary light-gathering source is a lens at the front, also known as the objective lens. This lens collects and refracts, or bends, light from distant objects to create a focused image.
Sealed telescope tube design
The refractor’s design is a sealed tube where light enters from the front, goes through the objective lens, and then focuses down the tube towards an eyepiece at the opposite end.
Types of refractor telescopes
Even within the category of refractor telescopes, there are different designs, each with its own strengths:
Achromatic refractor
Also known as an achromat, this telescope type employs a two-part objective lens made from different types of glass.
The lens design minimizes chromatic aberration, a type of distortion that occurs when different colors of light don’t converge at the same point.
Apochromatic refractor
Often referred to as apochromats or “apos,” these telescopes feature a lens typically made from three elements. They are designed to focus three wavelengths (typically red, green, and blue) into the same focal point, thereby reducing both chromatic and spherical aberrations.
This results in high-contrast, sharp images that make them a preferred choice for astrophotography and observations requiring great detail.
Advantages of refractor telescopes
Refractor telescopes offer several benefits, such as:
- The enclosed tube protects the optics from dust and reduces image-degrading air currents.
- Ease of use and minimal maintenance requirements make them ideal for beginners and those who prefer simplicity.
Disadvantages of a refractor telescope
Refractor telescopes do have a few downsides. Here are some of them:
- They tend to be more expensive, particularly for larger apertures, compared to other types of telescopes.
- Larger models can be quite heavy and long, making them less portable and requiring robust mounts.
What are refractor telescopes suitable for?
Refractor telescopes serve multiple purposes, including astrophotography, where they excel at capturing detailed images of galaxies and other deep-space objects.
Furthermore, these versatile telescopes can also be employed for terrestrial viewing, allowing users to observe distant terrestrial objects with clarity and precision.

Reflector telescopes
Reflector telescopes, also known as Newtonian reflectors, offer a different approach to observing the night sky. They use mirrors instead of lenses to gather light, providing several unique advantages.
Key features of reflector telescopes
Reflector telescopes have these distinct sets of characteristics:
Primary Mirror
They use a large mirror, known as the primary mirror, to collect light. The mirror reflects this light to a secondary mirror, which directs it to the eyepiece.
Open tube design
Unlike refractor telescopes, reflector telescopes have an open tube design, making them less prone to chromatic aberration.
Types of reflector telescopes
There are a few key types of reflector telescopes:
Newtonian reflector
Invented by Sir Isaac Newton, this design features a flat secondary mirror that directs light out to the side of the telescope, where it’s viewed with an eyepiece.
Dobsonian reflector
This is a simple, cost-effective design, typically large and placed on a simple, movable base, making it a favorite for beginners and for larger apertures.
Advantages of reflector telescopes
Reflector telescopes have these key advantages:
- They offer a large aperture at a lower cost than other telescope types, making them great for viewing faint, deep sky objects.
- They’re less prone to chromatic aberration, providing sharper images.
Disadvantages of reflector telescopes
There are a few downsides to reflector telescopes, and they are:
- The open tube design can allow dust and air to enter, requiring more maintenance.
- The mirrors may require regular alignment or “collimation.”
What are reflector telescopes suitable for?
Reflecting telescopes are particularly well-suited for observing deep-sky objects such as nebulae and galaxies, along with the ability to study bright objects like planets.
